In summary, the differing exposures of the cameras means very little to the raw image quality/noise comparisons when both have been post processed to about the same output brightness levels other than if the required exposures started to get down to a tenth of a second or slower where differing amount of hot pixels would start to make a difference.

Again, the secondary conclusion is that much too much concern is being made about this and much more than it deserves.

With respect, This whole analysis is really erroneous. It really is elemental knowledge that the more exposure the more light thus the less noise there will be. All images above base iso need to be "brightened", it is done by in camera hardware amplification, or software gain, or post processing in one's computer. But none of that really matters because in the end of the day you are comparing which camera does better in low light.

OMD mjust not receive more exposure in order to have a meaningful comparison.
